Patent GB-277549-A (GB)
Title: Improvements relating to the working of electrically-driven pumps
IPC: F04B49/06
Filed: 1927-02-08
Abstract: 277,549. Drysdale &, Co., Ltd., and Drysdale, J. W. W. Feb. 8, 1927. Regulating or controlling.-In duplex pumping apparatus one of two electrical pump units normally functions while the other is held in reserve and means are provided, dependent on the first pump unit and acting on its failure, to put into operation the reserve pump unit. With the arrangement and connections shown, the pump a driven by the motor f acts as the normal pumping unit and pump b driven by the motor g as the reserve unit. Automatic starters h, i are connected between the motors and the supply wires k. The discharge pipe c used for each pump unit is connected by a small-bore tube w to a pressure relay v the diaphragm of which operates bridging contacts u to connect or disconnect contacts n, o according as the pressure in the pipe is below or above a predetermined value. The relay moves with a snap action. A solenoid r is connected across the terminals of the motor f and operates a core carrying a contact q which bridges a gap p in the actuating circuit of the starter i. The core and contact q are normally held away from the break p by a spring z and their movement is retarded in each direction by a dash-pot t so that the relay v and bridge contacts u have finished their movement before the contact q is operated. Before operations are started, the relay v and contacts u, q are in the positions shown. When the current is switched on, the motor f and pump a are brought into operation, the circuit through the starter being completed at the contacts n. If conditions are right the pressure in the pipe c operates the relay v to remove the bridging contact u from the contacts n, o, after the solenoid 14 has closed a maintaining circuit for the starter h. The starter i is not energized in this case since the gap p is not bridged until after the relay v has operated. Should the pressure drop while the unit a, f is running, the relay v moves back to the position shown to complete the actuating circuit of the starter i which then operates to switch in the reserve set b, g. This will also occur if the normal set fails or is switched off by the depression of the " stop " button 3. If, during starting up the normal set fails to function, the reserve set will be switched in as soon as the contact q bridges the gap p. By operation of the switches 4 the gap p can be transferred to the actuating circuit of the starter h and the solenoid r to the terminals of the motor g thereby causing the set b, g to act as the normal set and the set a, f as the reserve set. Indicating devices 10 controlled from a circuit completed by the bridging contact u of the relay v show whether the pressure in the pipe c is above or below the predetermined value. The operation of the relay may depend upon the quantity of fluid supplied instead of its pressure, or it may depend on both.

Abstract: 539,193. Low temperature distillation retort and process. STEVENS, A. H. (Pittsburgh Coal Carbonization Co.). Feb. 27, 1940, No 3650. [Class 55 (i)] In the manufacture of coal balls in a rotary retort in which finely divided coal is fed through this retort and passes through pre-heating and plastic 'zones to a ball forming zone, air is admitted to the interior of the retort to provide for internal heating in addition to the external heating. The temperature in the retort varies from 805‹F. at the upper end to 1050‹F. at the discharge end. An inclined rotary retort 2 is enclosed by a stationary shell 8 and jacket 9 into which hot gases are supplied from a furnace 11, the gases entering the retort through conduits 13 and leaving for re-circulation through conduits 14, 15 and fan 16. The coal is fed through a casing 21 by a feed screw 22, and passes downwardly and over dams 27, 28, 29 which separate the pre-heating, plastic and ball forming zones, rifling 30 being provided to mix the charge and retard its downward movement. The residue is discharged by lifters 31 through an outlet 34 through which there is a free passage of air together with steam from pipe 38. The distillates are drawn off through outlet 18. The air reacts with the hydrocarbons and with the carbon formed in the retort to raise the temperature therein. Specifications 217,554, 246,118, 275,602, [all in Class 55 (i)], and 427,849 are referred to.
